Our silk pull-through oboe swabs cannot get stuck! Getting a swab stuck is a common problem with pull-through oboe swabs. However, our oboe swabs have an extra cord attached to the wide end of the swab so that they cannot get stuck. If one were to get a knot in it, it could be pulled back out the way it went in. These swabs are designed to be pulled all the way through the fully assembled instrument. We recommend our silk oboe swabs for all levels of players. Instructions for use: 1. Remove reed. 2. Drop ball chain through bell and pull swab through instrument.
